I RAY SMITH, or ELKINS, WEST VIRGINIA.

SOCKET.

Be it known that I, RAY SMITH, a citizen of the United States, residing at Elkins, in the county of Randolph and State of West Virginia, have invented certain new and useful Improvements in Sockets; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in sockets, and more particularly to that class adapted to be used in connection with incandescent electric lights; and my object is to provide means for making a positive connection between the socket and the bulb.

A further object is to provide means for readily assembling the parts of the socket together and locking them 'in-their assembled position, whereby casual displacement of the same will be avoided.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings, which are made a part of this application, Figure 1 is a central vertical sectional view through the socket. Fig. 2 is a transverse sectional view as seen from line 2 2, Fig. 1. Fig. 3 is a sectional view as seen from line 3 3 ,'Fig. 4 and Fig. 4 is a detail elevation of a portion of the wall of the socket, showing'the mechanism for securing the arts of the socket together.

Referringto drawings, in which simi- 7 lar reference-numerals designate correspond ing parts throughout theseveral views, 1 indicates a housing, to the hpper end of which is'secured a cap 2, said ca being of the usual or any preferred form an having a neck 3 at its upper end, through which are adapted to enter the circuit-wires. The lower edge of the cap 2 is provided with a circular flange 4,- end' of the housing 1 and is provide with inwardlyprojecting stems 5, which are adapted to enter L-s haped slots 6 in the upper edge ofthe housing 1.

, When the cap is being secured to the hous the stems 5 are introduced into the slots, and after the cap has been placed in position over the end of the housing" and turned to dispose the stems in the horizontal portions of the slots the keeper 7 is disposed over one Specification of Letters Patent.

of the stems 5 and securely holds the same in the horizontal portions of the slots 6, so that it will be impossible for the ca to become accidentally loosened fromthe iiousing. The keeper 7 is held iniplace on the inner surface of the housing 1 by means of ascrew elongated slot 9 in the side of the housing, so that whenit is desired to release the stem from the hooked end 10' of the keeper 7 the screw 8 is loosened, when the keeper, may be longitudinally elevated until the stem 5 is cap 2 may be rotated until the stems 5 register with the vertical portions of the slots 6, when the cap may be readily removed from its position.

Disposed within the upper end of the housing 1 is a head 11, said head being provided with a recess 12 at its lower end, in which isseated a frame 13, said frame being held in position within the recess 12 by means of a bolt '14 extending through an opening in the head '11 and engaging a screw threaded bore in the frame. Disposed between the depending portions 15 of the frame 13 is a contact-plate 16, said plate being provided at each end with an angular recess 17, in which are seated the depending portions 15 of the frame and bywhich means the contact plate 16 is held in position on the frame.

Extending through registering openings in the lower ends of the depending portions 15 is a shaft 18, upon which is rigidly secured a contact-key 19, said key being preferably obin general outline and provided in one edge thereof at its central portion with a depression 20, in which take flanges 21 on the shaft 18 and by which means the key is held rigid and caused to rotate with the shaft, the hub 22 of the key 19 and the flanges 21 serv ing to dispose the key centrally between the depending portions 15 of the frame 13. g

- A downward pressure is exerted upon the contact-plate 16 at all times through the medium of a spring 23, said spring being disosed between the contact-plate and the orizontal portion of the frame 13 and is held inposition therebetween by the lower extended end 24 of the bolt 14.

A threaded bulb-receiving socket 25 is disposed in the lower reduced end of the housin 1 and is secured therein in any preferred manner, as by bolts 26, the closed end of the socket being disposed over the recess 12, so

free'from the hooked end 10, after which the said screw being disposed through an a button 27, through the medium of which.

the shaft 18 may be rotated- The circuit through the incandescent bulb is' completed by means of an arm 28, said'arm being secured to the head 11 by means of a bolt or the like 29, the lower end of the arm being disposed through an opening 30 in the socket 25 and is providedwith a projection 31, against which is adapted to take a contact-point on the end of the incandescent bulb. The arm 28 is insulated from the socket 25 by means of any suitable insulating material, as mica, 32 disposed between the arm and closed portion of the socket. A circuit-wire 33 is secured to the arm 28 by means of abinding-screw or the like 34,

while the opposite wire 35 is secured to an extension 36 on the frame 13 by means of a suitable binding-screw 37, the wires being dis- 1posed through suitable channels 38 in the ead 11 and are directed outwardly through, the neck 3 of the cap 2. The inner surface of the housmg 1 is lined with suitable insulating material 39, by which means the parts carried by the head 11 are insulated. from the housin It will now be seen that I have provided a cheap and ecpnomical form of socket and one ected through the contact-plate'16, key h position an electric-circuit will be wherein the parts may be readily assembled or separated, as desired:

' What I claim isj ing a housing, a. cap for said housing, saidcap aving stems thereon adapted to enter slots in the housing, and a keeperlongitudinally 1 1. A device of the classdes'cribed comprismovable in said housing, said keeper having a hooked terminal adapted .to engage one of upon the housing. I

2. A device of the class describedcomprising a housing, a ca secured to said housing, a head within said the stems and prevent rotation of the cap ousing having a recess in the lower end thereof, a frame m said recess,

a bolt extending through the head and frame, the lower end of said bolt projectingbeyond the frame, a contact-plate having an angular recess in each end thereof, to receive the de-' pending portions of the frame a-sprin disposed between the contact-plate and and around the extended end of said bolt, a shaft rotatably mounted inthe' lower end of said depending portions, a contact-keyon said shaft and rigid therewith, a socket in the lower end of said housing and secured to said head, said socket being in the path of said ame key whereby when said key is turnedto one through the frame and socket. v

In testimony whereof I have signed-my name to this specification in the presence of two subscribing witnesses. Y,
